The only reason I want to change it is because its currently not working as it should be. I'm not sure if its because of the tune, I just feel like a blow through maf would yield a more precise measurement and be more stable when tuned properly. My main concern right now with a blow through maf is that I can't find anyone in my area who is confident tuning it.

are you tuned right now? any of the focus tuners can easily get you up and going.

you have some choices, you have tom at focuspower, randy at Fswerks and Fernando and RPS they all can send you a tune via email.
